ABSTRACT:
Wet cockle is minimized in aqueous-based, thermal ink-jet inks by adding to the ink at least one water-soluble substance, such as a solvent or salt, having a molecular weight of less than 200 grams/mole in an amount sufficient to reduce the mole fraction of water to a maximum value of about 0.5. Addition of the substance reduces wet paper cockle to a value that is less than the distance between the thermal ink-jet pen and the paper, thereby preventing a crash condition between the paper and the pen.
